Leishmaniasis can take one of three forms, each of which cause different symptoms:
- Cutaneous- formation of sores  or ulcers at the site of the insect bite
- Visceral- enlargement of the lymph nodes, liver, spleen, and bone marrow
- Mucosal- sores in mucous membranes of the mouth, nares, or pharynx 

Leishmaniasis is caused by 20 different protozoan parasites species of *Leishmania* and transmitted to humans through sand flies.
